\section{\class{wxGLCanvas}}\label{wxglcanvas}
|
|
|
|
wxGLCanvas is a class for displaying OpenGL graphics. There are
|
|
wrappers for OpenGL on Windows, and GTK+ and Motif.
|
|
|
|
To use this class, create a wxGLCanvas window, call \helpref{wxGLCanvas::SetCurrent}{wxglcanvassetcurrent}
|
|
to direct normal OpenGL commands to the window, and then call \helpref{wxGLCanvas::SwapBuffers}{wxglcanvasswapbuffers}
|
|
to show the OpenGL buffer on the window.
|
|
|
|
To switch wxGLCanvas support on under Windows, edit setup.h and set
|
|
{\tt wxUSE\_GLCANVAS} to $1$. You may also need to have to add
|
|
{\tt opengl32.lib} to the list of libraries your program is linked with. On
|
|
Unix, pass {\tt --with-opengl} to configure to compile using OpenGL or Mesa.
